Fronting Apache Tomcat with Apache Http

1. Download the Apache Tomcat connector

2. You will need to adjust the Apache Tomcat server.xml file to utilize the connector as follows:

• Shutdown tomcat
• Open server.xml for editing (/path/to/your/apache-tomcat/conf/server.xml)
• Comment out the default connector as shown below:

<!-- Define a non-SSL HTTP/1.1 Connector on port 8080
    <Connector port="8080" maxHttpHeaderSize="8192"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" redirectPort="8443" acceptCount="100"
               connectionTimeout="20000" disableUploadTimeout="true" URIEncoding="UTF-8"/> -->

• Now, uncomment the following connector block:

  No Format
  <!-- Define an AJP 1.3 Connector on port 8009 --> <Connector port="8009" enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />

• You may adjust the port (port="8009") if you wish.

3. Now, you need to do some configuring on Apache Httpd to connect to Tomcat. You have two options:

...

      Option #1 mod_jk

...

       Note: Configuring with IIS : http://tomcat.apache.org/connectors-doc/reference/iis.html

• Navigate to your Apache config directory

  No Format
  cd /path/to/apache/config

• Open httpd.conf for editing and locate the LoadModule section and make sure you have the mod_jk path defined (path may vary).

  No Format
  LoadModule jk_module "/usr/lib/httpd/modules/mod_jk.so"

• In the same file, httpd.conf, define the IfModule directive

  No Format
  <IfModule mod_jk.c> JkWorkersFile "/path/to/apache/config/workers.properties" JkLogFile "/path/to/apache/logs/mod_jk.log" JkLogLevel debug JkMount /*.jsp worker1 JkMount /path/to/portal/* worker1 </IfModule> JkMountCopy All

• Now, we need to configure the workers.properties file ( You may include the workers.properties file in the apache config directory, but the path must match with the httpd.conf file where you defined the JkWorkersFile path above.)

  No Format

  #Below is an example of a workers.properties file. # Define 1 real worker using ajp13 worker.list=worker1 # Set properties for worker1 (ajp13) worker.worker1.type=ajp13 worker.worker1.host=<your host address> # Set the port accordingly. You may adjust the port below worker.worker1.port=8443 # Below may vary as these are just examples of what can be included. worker.worker1.lbfactor=50 worker.worker1.cachesize=10 worker.worker1.cache_timeout=600 worker.worker1.socket_keepalive=1 worker.worker1.socket_timeout=300
